The map below shows changes in the aragonite saturation level of ocean surface waters between 1880 and 2012. [107] To pick one example, pteropods are a group of widely distributed swimming sea snails. For pteropods to create shells they require aragonite which is produced through carbonate ions and dissolved calcium. Pteropods are severely ...
